i'm using chat in codeigniter here i'm tring active users can display in chat whether user online or offline. tried following result empty. $this->session->all_userdata(); kindly me. if using database sessions, potentially verify login status using call ci_sessions table (or whatever have named it). can use simple query validate if have been browsing within last hour (or whatever) , validate them being online. sample sql query this: select from_unixtime(timestamp) 'timestamp' ci_sessions timestamp > unix_timestamp(date_add(curdate(),interval -1 hour)) order timestamp desc this return users active in last hour (the timestamp col updated each time page requested) you can grab users details out of 'data' column... $this->session->all_userdata() will not return logged in users available data of current logged in user

i understand java projects using gradle publishing reusable code publishing maven's pom.xml file along side jar file. i'm wondering gradle store dependency list if library not published using neither ivy nor maven. moreover, gradle can used not jvm-based project, can used build non-jvm project, not use maven or ivy. i've read chapter 23. dependency management doesn't give clue how gradle can publish java library without maven or ivy. transitive dependencies native projects in gradle not possible of gradle 2.13. you need implement own plugin somehow store/retrieve , process such metadata , use them correctly (resolve, download , put files correct directories). we plan implement similar functionality. closest solution maven nar plugin .

i have small library made stand along except 1 optional method in class requires imagemagick. looking make possible not compile method if machine not have imagemagick installed; rather failing. issue header still have method defined (though not compiled). there way remove method header using cmake or other approach? wrap definition in preprocessor definition: #ifdef have_imagemagick void myfunctiondefinition(void); #endif then, in cmake, if imagemagick found, add definition project. cmake pass definition command line of compiler, define preprocessor token. if(imagemagick_found) # or whatever cmake variable holds info add_definitions(-dhave_imagemagick) endif() alternatively, if have many such defines, consider include file hold of these configurations. cmake command configure_file can expand out entire file's worth of configuration statements @ once.

i trying triangulated vtkpolydata mlab.contour3d plot. using mayavi because seems fastest way minimal surfaces triangulated properly. need vtkpolydata because want save .stl file. here mwe of code: import numpy np mayavi import mlab def fun(x, y, z): return np.cos(x) + np.cos(y) + np.cos(z) x, y, z = np.mgrid[-1:1:100j, -1:1:100j, -1:1:100j] contour = mlab.contour3d(x, y, z, fun) mlab.show() what mayavi surface triangulated , displayed using vtk (or tvtk ), should possible vtkpolydata there. way found far use mlab.savefig(test.obj) export .obj-file (which bad, because takes time save file everytime mayavi ui opens) , import file again using vtkobjreader , gives me vtkpolydata want. does know more straight-forward way this? edit: clarify problem bit more: can access data visualization e.g. mayavi.tools.pipeline.get_vtk_src() , comes in form of vtkimagedata . if knows way convert vtkpolydata , solution. by total coincidence found solution. impor

i working on app cms-functionality client can match arbitrary paths articles. now, use route globbing match html request , check in controller if have article show. if no article present, want send request route resolution flow, search other potential matches. i imagine there should exception that, can't figure out. it's not routingerror . the configuration file: config/routes.rb runs top-to-bottom when defining application routes. need define catch-all @ top of file. i'd recommend using sort of constraint (so can cache result). example, solution may like: # config/routes.rb '*', to: 'article#show', constraints: articleconstraint.new # lib/article_constraint.rb class articleconstraint def matches? # trivial example... make better, e.g. use cacheing! article.exists?(name: request.path) end end
